That is what I get for an ADuM1441 idling 99% of the time with refresh disabled, and only running one side of the part. It runs at 0.001mA for most of the time, and a lithium cell is 225mAH, that comes out as a lot of hours, but that is what you want. The Battery is supposed to be running the application , not the interface.
